EXTENSION-CORD CONNECTER.

.Application filed August 1,1925. Serial No. 47,551.

This invention relates to a connector which is not necessarily limited to, but. particularly, adapted for use in connection with extension sets used in telephone or radio work wherein it is desired to carry, for example, a loud speaker into a different room from that containing a radio receiving setand be able to connect a loudspeaker or pair of head phones to the extension cord coming from the radio .set.

The principal object of my invention 1s to provide an extension cord connecter which is extremely simple in design, hence, cheap to manufacture, but, one that is highlyetiicient in operation and artistic in design.

Another object of my invention is to pro vide a conneeter in which the cord terminals are securely held in position within the connecter to prevent accidental withdrawal of the terminals therefrom, but, in which the varrangement is such that the operator, by proper application of a slightforce, may readily withdraw the terminal.

Another object of my invention is to provide a connector in which the interior parts are so constructed as to insure the proper alignment of the spring member so that the terminals may be readily inserted.

These and other objects will be apparent to one skilled in this art after a reading of the specification taken in connection with the annexed drawing'wherein Figure 1 is a plan view of the assembled connecte'r.

Figure 2 is an end view ofFig. 1.

Figure 8 is a view of the connecter shown in Fig. '1, but with one half of the eonneeter removed and .showing but one pair of the terminals with the associated spring.

Figure 4 is a section on the line ll of r v I Figure 5 is a. plan View of the spring shown in Fig. 3.

Figure 6 is a partial view of a preferred form of construction of the interior part of. one of the connecter members.

In the drawing wherein like. numbers refer to corresponding parts in the various views, the connect er comprises two pieces 1 and 2 preferably of good insulating material. Thepieces .1 and 2 are, in the ordinary course of manufacture, molded so as to form a chamber within the two pieces when they are put together. Each of the two pieces 1 and ,2 is preferably provided with a central rib to strengthen the members 1 and 2 as well as to act as a protection between the connecting members within the chamber. Referring particularly to Figs. 3 and l each of the members 1 and 2 is provided with a groove 1- disposed on either side of each of said pieces 1 and 2.

A spring 5 is provided with a central arranged enlarged portion 6 having shoulders 7 and 8. These shouldered portions? and 8 are adapted to fit within the grooves l as clearly indicated in Fig. 4, the spring 5 being mounted within the pieces 1 and 2 in an edgewise manner. The springs 5 extend nearly the full length of the chamber within the pieces 1 and 2 and are formed so as to engage cord conductor tips 9 and 10, one at each end of the spring.

As will be seen from Fig. 2, the pieces 1 and 2 have cut away portions at the end to form orifices 11 when the pieces are put together. In assembling the eonnecter the pair of springs 5 are set in position in the grooves at in one of the pieces and the other insulating piece is then placed over the first assembly and a pair of rivets or eyelets 12 are passed through the holes 13 and riveted or spun over thereby completing the connecter.

V I prefer to use the formshown in Fig. 6 in which each end, of the pieces 1 and 2, is provided with aplurality of shoulders. The shoulders 14 are utilized as stop or retaining members for the ends 15 of the springs 5 thereby positioning the springs so that the contact portion 16 thereof is always in the same position with respect to the orifice whereby the cord tip 10 can be readily inserted within the connecter. Another shoulder 17 adjacent the shoulder 14 isused for the purpose of engaging the end of the cord tip 10 after it has been inserted within the connecter. The end of the spring pushing against the cord tip 10- will move this so as to cause the end thereof, to pass behind the shoulders l'T thereby preventing accidental straining on thecord from drawing the tip from the connecter. The features' of these two shoulders and particularly the firstherein described is described and broadly claimed in my pending application Serial No. 45,028 filed July '21; 1925.

From the foregoing description it will be observed that my complete connecter comprises two piecesof insulating material, two

double ended springs and at least one rivet or eyelet, or some equivalent means for fastening the two pieces 1 and 2 together. Furtheri'nore, it will be observed that no screws are required to hold the spring 5 in position. within the connecter and neither are any screws used in the construction of the complete connecter; consequently, the great ease with which the connecter may be assembled and its extreme simplicity will be readily apparent.

My invention, of course, it susceptible to certain changes in the details without departing from the spirit of the same or the scope of the appended claims.
